Embodiment approach
[0111] In this embodiment, the server fuses the time-domain audio features and the frequency-domain audio features of the multiple audio frames by adding together to obtain the initial audio features of the target video, and rolling the initial audio features The product is used to further fuse the time-domain audio features and frequency-domain audio features, and the obtained audio features can more accurately express the audio characteristics of the target video.
[0112] For example, when the server extracts time-domain audio features through multiple one-dimensional convolution kernels and extracts frequency-domain audio features through multiple two-dimensional convolution kernels, the dimension of the obtained time-domain audio features is one-dimensional , the dimension of frequency domain audio features is two-dimensional. In this case, the server upsamples the time-domain audio features of the plurality of audio frames, and changes the one-dimensional time-domain aud...

The present application discloses a method, device, device and storage medium for determining the insertion time point of background music, which can be applied to scenarios such as background music insertion, artificial intelligence, and vehicle-mounted in computer technology. In the embodiments of the present application, the audio features and image features of the target video are combined to determine the video features of the target video, and the video features can more accurately represent the content of the target video. The video features are encoded based on the attention mechanism to obtain multiple target parameters. Based on the target parameters of the multiple time points, a candidate time point is determined from the multiple time points, and the candidate time point is a time point at which background music can be inserted into the target video. In the above process of determining the candidate time point, due to the combination of the attention mechanism, the determined candidate time point is more accurate. At the same time, when the background music is inserted, the efficiency of inserting the background music into the video is improved under the premise of ensuring the accuracy.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular, to a method, apparatus, device and storage medium for determining the insertion time point of background music. Background technique [0002] With the development of Internet technology, watching video has become a common form of entertainment. In the process of video production, background music is often inserted into the video, and the background music is used to enhance the atmosphere of the video, thereby improving the viewing effect of the video. [0003] In the related art, the insertion time point of background music is realized by a method of manual selection, that is, in the process of watching a video, the video producer determines the time point at which background music is inserted into the video according to the content of the video. [0004] However, the manual selection method consumes a lot of time and human resources, resulting in low efficiency in...
